The 23 year old has been strongly linked with a possible Old Trafford switch and this source believes that the defender is ready for force the situation by pushing for a deal to be struck.

Man United have been very weak defensively this term, suffering with a surfeit of injury concerns that have seen the likes of Phil Jones, Nemanja Vidic and Chris Smalling all spend time out on the sidelines. Inconsistent displays from Rio Ferdinand and Jonny Evans have further exacerbated the issue and a move to bring in a solid defender in January may well be on the cards for Sir Alex Ferguson.

Hummels has been the mainstay of Jurgen Klopp’s back-line for the past three seasons and the former Bayern Munich man has helped the Westfalenstadion side to back to back Bundesliga titles. However this term he has seen his former employers open up a massive lead at the top of the table which could well lead to the German international considering his options.

Man United have conceded 17 goals in 12 Premier League matches and have kept just two clean sheets thus far this season.
